Point Transect Method
Point Transect Method
The point transect method is a technique based on point sampling to determine cover. To follow this method, point readings are taken at either systematic or random locations along a tape that is extended to create a transect across the site. A variety of devices, including sighting tubes, bayonets, and plumb-bobs have been used to ensure a vertical reading of the point through the tape.
Arrangement of Points
Arrangement of Points
Observations based on single points, such as the step point method, tend to take less time to record and give a more precise estimate of cover than do the same number of points sampled as a group, such as the point frame method.

Plant Dimensions
Many different attributes describing plant dimensions can be used to determine plant biomass. Measurements on plant height, plant basal area, twig length and diameter, trunk diameter, canopy cover, or canopy volume, are all used as indirect methods to estimate biomass.
